Why don't we use MSE as a reconstruction loss for VAE ?

Description

Hi,

I am wondering if there is a theoretical reason for using BCE as a reconstruction loss for variation auto-encoders ? Can't we simply use MSE or norm-based reconstruction loss instead ?

Best Regards

Contributor guide

Research direction
Review the derivation of the VAE loss (ELBO). The choice between BCE and MSE corresponds to assuming Bernoulli or Gaussian likelihood for the reconstruction. Check the original VAE paper (Kingma & Welling) and resources on variational inference.
